The Effect of Lead Oxide on the Change in Gamma Ray Protection Parameters of Bismuth Oxide

Abstract

The aim of this study is to investigate the gamma ray radiation absorption properties of bismuth oxide (Bi2O3), and determine the effect of lead oxide (PbO) additive in the shielding of Bi2O3. For this reason, the radiation absorption parameters such as mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half value layer (HVL), tenth value layer (TVL) and mean free path (mfp) were calculated theoretically for the Bi2O3, PbO, and 50% Bi2O3-50%PbO. The all parameters results were obtained by using the GATE/Geant4 (Geant4 Application for Tomographic Emission) simulation code in energy range 511 keV, 662 keV, 1173 keV, 1274 keV, and 1332 keV. Also, the gamma ray protection parameters were calculated by using the XCOM program in the energy range from 1 keV to 1 GeV. Thus, the simulated the GATE/Geant4 results were tested for correctness using the XCOM program. On the other hand, theoretically were calculated values of all parameters of the shielding materials were compared with each other. These results indicate that the GATE/Geant4 results were in good agreement with the XCOM results.

Determination of The Radiation Shielding Performance of MoO2 Addition On PbO by Monte Carlo Simulation

“…Many studies have focused on glass materials for gamma ray shielding [12][13][14][15][16][17][18] In addition to experimental studies, simulation programs have an important place in armoring studies in terms of accessibility and ease of application. In recent years, the results obtained with the Monte Carlo simulation codes have been compared with the experimental data [19], thus accelerating the search for alternative materials [19][20][21][22][23][24][25][26].…”
